" Nowadays," says Dr Lock in his Preface, " rubber enters so intimately 

 into the daily life of almost everyone, that there will probably be few to 

 whom the romance of rubber entirely fails to make an appeal." 



To make the book suitable to as wide a circle of readers as possible the 

 author has aimed at combining an accurate account of the scientific side of 

 rubber planting with a certain amount of practical information for the 

 benefit of the prospective planter. 



"Each subject is dealt with concisely and the facts presented in an interesting and 

 straightforward manner. The book may be recommended as one of the best all-round 

 treatises on rubber yet written. ..no questions of importance have been omitted, and 

 coming as it does from the pen of such a well-known expert on rubber, readers will 

 have every confidence that the information represents the latest knowledge and ideas on 

 any point." — The Financial Times 



"...Should meet with a wide welcome. The authoritative account given by 

 Dr Lock is not only extremely interesting to read, but should also be of real value to 

 the prospective rubber planter and to those who wish to interpret the prospectus of a 



rubber company The description of the industry gains much by the illustrations, 



which include. ..photographs. ..and excellent line-drawings, specially made." — Knonv-
